Application tiled February 23. 1906. Seri'd No. 302.404.

l`nited States, 4and residents of the borough' ol5 Brooklyn, in thc citj.' and State ol' New York, have invented a new and useful Tm provement in Shcet-liling, ol` which the iollowing is a specilication.

(lur invention relates` to an improvcnient in sheet-piling, and has for its object to provide a composite sheet-piling comprising alternating woodplanks and metal beams which are interlocked in a very simple and ell'eclive manner, so as to l'orin a strong and water-tifgght wall suitable for all purposes to which sheet-piling is :nlaptcd-suclh for instance, as in the construction of' sea \\'alls, docks, pier-foundations, &c. v

A further object is to provide a composito sheet-pilingwhich can be set up at a less expense than has heretofore been possible, the number ot' parts beingl reduced to a minimum. ln the accompanying drawings, Figure 1 represents a section ot'- our improved *conn posile sheet-piling in top plan. Fig. 2 is a side View ol the saine, portions of they piling intermediate the top and bottomI 'being broken away; and `Fig. 3 is an enlarged horizontal section through one ot the metal beams and adjacent portions oi two ol the Awood planks, showing more clem-1).* the inte-ilockingoi the saine irrespective of the angular position of the planks with respect to each other within a limited scope..

The-shcetpiling is composed of alternating wood planks and metal beams 1 and 2. The wood planks may be provided at their lower ends with sharpened points 3 for facilitating `the drivingof the planks into the ground. e

Each. metal beam is shown as comprising a central longitudinal web 4, from one edge of which two opposite long jaws `5 extend and from the. other edge of which two opposite short jaws 6 extend. The opposite jaws of each beam have portions thereof embedded in the opposite faces of the adjacent planks. In the present instance We have shown this result as accomplished bv turning the edges of each pair of jaws 5 and 6 inwardly toward each other, the. distance between the edges of said `aws being less than the thickness of the Woo plank.

lhc reason for making the jaw shorter than the jaw Sis to permit the wood plank to be interlocked with the metal beam irrespective of its angular position with respect y to the same within a limited scope.

When the piling is set up, the edges of each pan of- Jaws 5 and 6 of the metal beams will be embedded in the opposite `faces of each wood plank l, with the side edge'of the plank spaced from and inclosed b v the said jaws' and the wena. so that the side edge of the plank is eil'eetuallv protected, and also a cavity is formed within the metal beam.

The tendciiosv of the wood to swell when the pilingT is used in connection with hydraulic work will more l`ullY and completely interlock the wood planks and metal bea-ms, and thus make the jf, ints,waterproof.

ll it is desired to tighten the piling, the

.spaces around the edges of the Wood lanks within the metal 'beams'may be fille with sand, clay, cement, or other suitable material 7.

B v constructing a sheet-piling as herein set forth the use of additional mea-ns for interlocking tlie planks and beams is obviated, and it will bc seen that wood planks of ordinar)r construction not specifically shaped may be used, the edges of the planks being ell'cctually protected by the metal beams. Also by turning the edges of each pair of jaws inwardly toward eachother a cavity is formed around theside edge of the wooden plank, and by making 011e aw shorter than` the other the plank may be turned at au angle to the beam7 so that a corner may be turned in Vthe sheet-piling without the useog.

spccially-shaped beams or planks therefor.

What we claim 1sf 1. A composite sheet-piling comprising al.- I ternatiner wood lanks and metal beams arranged Tongitu inally and interlocked together, the metal beams being provided with jaws having ortions thereof `embedded in the opposite ilaccs. of the wood planks along their side edges. l

2. A composite sheet-piling comprising alternating wood lanks and metal cams ar ranged. ongitu inally and .interlocked together, the metal beams -be''ng provided with pairs of jaws embedded in the opposite faces of the Wood planks for protecting the edges ofthe planks along their side edges.y

, 3. A composite sheetfpiling' comprising al- -being so arranged as to leave cavities around .opposite faces of the Wood planks the parts `terloeked together; the metal beams being provided with. pairs -of jaws having theiri edges embedded in tbcl opposite faces of the ternatin -Wood planks and metal beams interlocke together, the metal beams being provided Witfi pairs of aws embedded in tiie opposite faces of the Wood planks the parts theedges of the planks within the said beams.

.4.. A composite sheet-piling comprising alternatine' wood planksand iiietal vbeams interlocked together, the metal beams being provided with pairs of jawsenibedded in tire being so arranged as toleave cavities around the ed es of the larikswithin the said beams and a illing for said cavities.

5. A composite sheet-piling comprising al teriiatiiig wood lanksaiid metal beanie arranged ongitucinally and interloelred togetiiei, the metal beams being provided with. pairs y of jaws having their edges embedded in the opposite faces of\tlie wood. planksi along their side edges..v f r 6. eoinpositeslieet-piling comprising al- 1 gernating'wood planks and inetal beams in fwoed planksj'one of tire jaws of each pair bei ing shorter than the other jaw. l

l7. Ajcoinposite sheet-piling comprising alternating wood planks and metal beams arranged longitudinally 4and inteiloeked together, tire metal beams being provided witli pairs of jaws having their edges turned iii? wardly and embedded in tire op osite faces of the wood planks along their si( e edges.

8. A composite smet-pilingv comprising alternating wood lanks and metal eanis arranged longiturinally and intcrlocked toget'ner, caen metal beam being provided with two pairs of' ]aws having their edges embedded in tiie opposite faces of two adjacent Witnesses for Paul A.. Scliuoliart:
